OpenShift DeploymentBallerina supports generating the OpenShift Route, BuildConfig, and ImageStream artifacts based on annotations.
Docker image of the Ballerina service is built using the BuildConfig, which then can be used by the generated Kubernetes Deployment.
A generated OpenShift Route exposes the Kubernetes Service of the Ballerina Service.
This example deploys an HTTP service, which responses “Hello” followed by a name. |
